Abstract
An encoder and decoder using LDPC-CC are provided, which avoid lowering the transmission efficiency of information while not deteriorating error correction performance, even at termination; and an associated encoding method is provided. A termination sequence length determining unit determines the sequence length of a transmitted termination sequence added to the end of an information sequence, according to the information length (information size) and encoding rate of the information sequence. A parity calculation unit carries out LDPC-CC coding on the information sequence and the known-information sequence necessary for generating a termination sequence of the determined termination sequence length, and calculates a parity sequence.
